docker安装Oracle11g数据库

最近公司项目需要用到oracle数据库，为方面同事开发，于是在公司阿里云服务器上用docker安装了一个oracle11g，给同事开发测试使用。
1、下载oracle11g的镜像文件
这里我使用的镜像文件是：registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g，这个镜像文件有6.85G这么大，下载需要几分钟的时间。

[root@iZbp13sno1lc2yxlhjc4b3Z ~]# docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
[root@iZbp13sno1lc2yxlhjc4b3Z ~]# docker images
REPOSITORY                                             TAG                 IMAGE ID            CREATED             SIZE
registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g   latest              3fa112fd3642        4 years ago         6.85GB

2、创建运行oracle容器

[root@iZbp13sno1lc2yxlhjc4b3Z ~]#docker run -d -p 1521:1521 --name oracle11g registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

3、配置oracle
进入oracle容器，配置环境变量。
分别在在/etc/profile和/home/oracle/.bashrc文件末尾添加环境变量。
在/etc/profile设置oracle环境变量：

[root@iZbp13sno1lc2yxlhjc4b3Z ~]# docker exec -it oracle11g bash
[oracle@753d0436c2f1 /]$ vi /etc/profile
# /etc/profile
...
export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH

在/home/oracle/.bashrc设置oracle环境变量：

[oracle@753d0436c2f1 /]$ vi /home/oracle/.bashrc
# .bashrc
...
export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH

测试数据库连接：

[oracle@753d0436c2f1 /]$ sqlplus /nolog

SQL*Plus: Release 11.2.0.1.0 Production on Thu May 14 20:57:07 2020

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

SQL> conn / as sysdba
Connected.
SQL> 

4、修改oracle用户密码
修改sys、system等管理员账户密码

SQL> alter user system identified by system;

User altered.

SQL> alter user sys identified by sys;

User altered.

SQL> 

查看oracle数据库状态、实例名等信息：

[oracle@753d0436c2f1 /]$ lsnrctl status

根据状态信息可知，实例名为：helowin。

5、PLSQL客户端连接
用户：sys，密码：sys，数据库：你的IP地址/helowin，以sysdba角色登录即可。
